SPECIFICATION forming part of Letters Patent No. 254,879, dated March 14, 1882, Application filed May 28, 1881. (Model.)

/ To all whom it may concern:

Be it known that I, WILLIAM LOTTRIDGE, of Osage, in the county of Mitchell and State of Iowa, have invented certain new and useful Improvements in GrainBinders, ot' which the following is a specitication.

My .invention mainly relates to improvements in automatic binders of the class in which cord is employed to secure the bundles [o ot' grain, and in which the grain is bound at or upon thc inner end of the grain-plattorm, or an extension thereof', on or substantially in the same level as the platform. Some of my improvements, especially the cord manipulating or tying mechanism, are, however, applicableto machines of various types.

My improvements consist in a novel organization ot' mechanism, and in certain combinations ot' devices, which hereinafter lirst are 2o fully described, and then specifically desig-` nated by the claims.

In the accompanying dra-wings, which represent so much ot' a harvester as is deemed necessary to illustrate my invention, 1= have shown all my improvements embodied in the best way now known to me. Some ot' them may, however, be used without the others, as by ingrafting essential tentures ot' my invention upon machines di'eringin some respects from go the one in this instance shown and hereinafter particularly described, and which resembles somewhat that in connection with wlxichare 4shown certain improvements heretofore invented by me, and patented December 17,

Figure 1 is a plan or top view ot' the machine with the platform partly broken away. Fig. 2 is a view partly in front elevation and partly in vertical section, as indicated by the 4o line 2 2 of Fig. 1. Fig. 3 is a View partly in side elevation and partly in vertical section, as indicated by the line 3 3 ot' Fig. 1, looking from the inner or platform side ofthe machine. Fig. 4 is a view in detail, showing a rear elevationof theinner back corner ofthe main frame and the adjacent portion of the platform, and in part the devices for eveniugtthe butts of the grain as it is being delivered to the point where it is bound. Fig. 5 is a view partly in side elevatiouand partly in section 5o on the line5 5 ofFig.1,looking trom the outer or drive-wheel side ot' the machine. Fig. 6 is a view in elevation of the grain-wheel end of the platform. Fig. 7 is a view partly in plan Y and partly in horizontal section, as. in partindicated by the line 7 7 ot' Fig. 2, showing details of the binding mechanism, starting devices, and features of the bundling or'gavelcompressing devices. Fig. S is a view 'partly in front elevation and partly in section, as in- 6o dicated by the lilies 8 8 of Figs. land 3,show ing details of the binding mechanism, stopping and starting devices. Fig. 9` is a view partly in side elevation and partly in section on the. line 9 9 of Fig. 2, showing the recipro- 65 eating cord-carrying needle or binder-arm, and in part the devices by which the movements ofthis arm are caused to stop and start the gavel gatherer or grain compressor, rake. Fig. 10 is a view partly in rear elevation and -7o partly in section on the line 10 10 of Fig. 11, showing parts of the bundling and tying mechan ism,with a gavel represented as encompassed by the cord, and the parts in the positions occupied just after the band ends have passed to or been engaged by the tyer or knotting devices.

Fig. 17 is a longitudinal view, partly in section, of the two rotating and inde- 9o pendently-reciprocating cord-engaging hooks ot' the hnotting mechanism and their. immedh ate attachments or connections, the rotating tubular shank or mandrel (about whichtlle cord is looped, within which the inner hook re-` 954 ciprocates, and on which the carrier of the outer hook is supported) being shown in section and the parts represen ted as in their inoperative position, or ready to have the cord passed around the mandrel; Fig. 18, a view generally similar to Fig. 17, the outerhook being shown as advanced upon the rotating mandrel or supporting tubular shank into the position assumed by it just after the ends of the band or cord have been passed to or pressed against the mandrel. Figs. 19 to 35, inclusive, are diagrams representing the various positions of the cordengaging hooks or" the knotter and the positions assumed by the band ends in the different stages of the knotting operation. Fig. 36 is a view representinga portion of aband about a bundle, with the knot completed. Fig. 37 is a plan view with parts broken away, showing details of the cord placing and griping or holding devices beneath the plane of the cord-engaging hooks, with the needlebinder-arm in section, the parts being represented as in the positions assumed shortly after beginning to engage and act upon the band in securing it about a bundle; Fig. 38, a vertical section on the line 38 3S of Fig. 37, with parts shown in elevation; Fig. 39, a view in elevation of the inner end of the outer member of the gripcr or cord-holding slide and its immediate connections, the lower' cord-controller or placing-finger being in part represented in section and shown as in a position occupied by it at a sta-ge in the operation prior to that illustrated by the two preceding figures; Fig. 40, a view generally similar to that represented by Fig. 39,

but with the parts in position assumed at a later stage in the tying operation; Fig. 4l, a plan view generally similar to that represented by Fig. 37, but with the parts in different positions, themaiu member or inner slide of the griper being advanced and the outer slide retracted, and both ends of the band griped side by side between the adjacent surfaces of the-ends of the two slides, that end of the band before held beneath the main griper-slide being released at such place; Fig. 42, a lsection on the line 42 42 of Fig. 41. Figs. 43 and 44 are views generally similar to those represented by Figs. 39 and 4() at stages in the operation prior to andjust after severing the band, Fig. 44 showing the end oi' the cord as clamped beneath the main member orinner slide ofthe griper,readyforsecuringanother bundle. Figs. 45 and 46 are views in side elevation and plan, with parts in section, showing guards or holders to prevent scattering or spreading of the grainaccumulated to form a gavel.

The machine is carried upon a main supporting anddriving wheel, A, and a verticallyadjustable platform-supportin g or grain wheel, A', which is journaled between connected bars a a., or in a slot in a single bar hinged at front to the outer end of the finger-beam or adjacent portion of the platform A2, so as to vibrate vertically, and ad justably secured at rear by means of a pin, c', in holes in curved standards a2 a2, secured to the rear outer corner of the platform.. A handle, a3, admits of the ready raising and lowering of the levers or bar a c in adjusting the grain-wheel to the desired height. The driving-wheel is secured fast upon its axle, which is suitably mounted in the main frame beams or transverse bars B B. The driving-wheel imparts motion to toothed endless chains b, of any desired number, working in slots in the platform. The shaft B', geared with the axle of the driving-wheel, is provided with a sprocket-wheel, around which passes a chain, B3, to communicate the motion to the toothed endless chains in the manner and by means farther ou fully to be explained. The driving-wheel also imparts motion to the binding mechanism through or by way ofa sprocketwheel,fb', on the main axle anda chain, B2, passing over a sprocket-wheel, b2, in manner hereinaiter fully to .be described.

The above-mentioned features to the extent described, excepting the way of mounting the grain-wheel, are generally similar to or substantially the same as corresponding` parts in the machine shown in the before-referred-to Patent No. 2ll,(l27.

Instead of two series oi'toothed endless chains working in the platform-slots, as in the abovementioned patent, l in this instance employ but a single series ofthe chains b, mounted on the shafts (l (l, the inner one of which shafts is driven by a chain, C', from a sprocket-pulley, b3, loose on a shaft, C2, which pulleyV is in turn driven by the chain B3, which passes around a pulley, b4, fast to the pulley b3, as well as around a pulley on the rear end of the shaft B', operated from the driving-wheel by the bevel-gears G30, respectively on the outer end of the main axle und on theinner or front end of said shaft. The shafts B' and G2 are mounted respectively at the outer rear corner and near the inner rear corner ot' the-trame of the machine.

A positively-actuated horizontally-vibrating gavel regulator or evener, D, to adjust thegrain as it is delivered to the inner end of the platform on the way to be bound, is shown (see Figsrl and 5) as formed of a bent or angular plate, pivoted by its base at d, near its outer end and inner edge, so that as vibrated the vertical part of the evener will repeatedly strike or ICO IIO

pat the butts of the grain and even the stalks.

4while the opposite arm of the lever is pivoted to the rear end of the pitman c', which at front is pivoted tothe evener D, by preference tothe under side of the base or horizontal portion thereof. The pitman may, if preferred, be extended and bent upward in front of the evener, and adjustably secured thereto by a set-screw and horizontal slotin the upright portion of 13o the evener. By adjustably connectin g the pitman with this evener, preferably by a screw, d,

to tit any one of a series of holes in the base of theevener, (see Fig. 5,).the evener may be adjusted to suit variations in the lengt-l1 of grain, and this without interfering with the proper delivery of the grain as carried inward by the delivery belts or chai'ns and a rake or gavel-gatherer, D2, so as to bring the butts iuside of the upright portion of the evener for acting on the projecting stalks of a bundle as the grain is accumulated upon the bindingtable or inner grain-receptacle portieri, D', of the platform.

The rake or gatherer D2 and a grain-arrester or gavel-sizing stoparii'i, D3, (between which arrester and gatherer the gavel is accumulated, compressed, and its size regulated upon the bindingtable,) are operated in the manner and by the means hereinafter to be explained.

The before-mentioned driven sprocket-wh eel b2 for operating the tying devices of the binding mechanism is mounted loosely on the end of a shaft, E, housed in a bearing at the front ofthe inner bar of the pair of frame-bars B B. The hub or sleeve of the pulley inside said bearing has fixed to it a clutchcollar or member, e, of an ordinary clutch-coupling. Near itsinnerend-theend opposite thatto which the chain-wheel b2 is fixed-the shaft E is mounted in a bearing, e', secured to and projecting,r backward from the front top frame-bar, E', and at its inner end this shaft carries a bevel-tnion, E2. This bevel-pinion is caused to rotate when the-movable clutch-section or sliding membel` e2 ofthe clutch-coupling is engaged, in manner to be described farther on, with the member ofthe clutch carried bythe pulley b2. The pinion E2 meshes with the lower one, e3, ot' a pair of tiXedly-connected bevel-pinions, E3 ci', on the upper end of a tyer-actnating shaft, F. The upper one, E, of the pair of pinions meshes with a corresponding pinion, F', on a shaft, F2, for actuatingavertically-reciprocatingcordcarrying needle or binderarm, G. The shafts F and F2 are mounted at their adjacent ends respectively in bearingsfand f' on a. bracket,

72, secured to the frame-bar E', and to which bracket the bearing e of the shaft Eis also secured.

The vertically-reciprocating needle or binderarm G is actuated by a crank, H, on the inner end of the revolving shaft F2, apin or roller, l1., on the crank working in an irregular slot or camway, H', in a plate fixed to the side of the binder-arm. The cord g passes along the binder-arm by a suitable channel or groove ruiming lengthwise thereof, and the binderarm is supported by a standard or upright, G', and suitable engaging-clips or guide-lugs, g', in any desired number. A roller, g4, is provided near the point of the binderarm for the cord to pass around, .as usual. The binderarm support G' and the inner bearing, h', for the actuatingshaft F2 are secured respectively upon inclined trarne-bars H2 H3, between which the binder-arm reciprocates.

. The before-mentioned grain-arrester arm D3 is pivoted near its upper end to the outer or free end of a vibrating arm, G2, which is pivoted at g2 by its inner or heel end to the frame.. bar H3. rlhis vertically-vibratingarm G2passes along one side of thesupporting-stalndard G', and is connected by a link, h2, with the upper end of a vertically-reciprocating bar, g3, supported and guided in a bracket, G3, securedV tothe binder-arm support G'. At the lower end of this bar g3 there is a lateral projection or stud, h3, beneath which passes a disk or roller, h4, on the roller or pin h of the crank H, inside of the camway H', so as to elevate the bar, and with it the grain-arrester arm D2, when the crank is ascending from its lowermost position, at which time the binder-arm is also ascending, and in this way free a bound bundle, as will farther on more clearly appear. A spring, d', connected with the upper end of the arrester-arm, acts with a constant tendency to` swing the arrester-arm against the pressure of the grain being accumulated and compressed, or to hold said arm in the position normally occupied by it, as when no grain is upon the binding table.

The before-mentioned intermittently-actuated gavel-gatherer or rake D2, for repeatedly acting on the grain as collected by the endless belts of the platform, is thrown into and out of operation automatically, as will now be described, referring to Figs. l, 2, 3, and 7 ofthe drawings.

The rakchead or gatherer proper (which may consist of two or more teeth) is secured to the outer end ofan elcngating and lcontracting orjointed shank or handle, I, which at its inner or heel end is in this instance pivoted to a swinging pendent arm or vibrating link, i, shown as supported by the frame-bar H3. A jointed controller-arm or link-rod, l", is connected at one end by a pivot with the rakeshank I, and at thev other end this link is piv oted to a crank-arm or cam-plate, I2, fastened fo n the inner end ofthe shaft G2, which is supportedA near its cam or crankplate in a bearing ina bracket, 2. Ordinarily, or inlits normal or operative condition, the shaft C2 is caused to revolve with its pulleys I;3 b4, by means of a clutch-couplingconnecting the sleeve or hub of the pulleys with the shaft. As the shaft revolves the rake is drawn outward and moved backward by the link 1', and the rake-head is lifted on the outward stroke and held above the grain by the action ofthe cam-shaped crank or plate l2 on a bent guide or lifter arm, 13. As the crank-plate is revolved and the rake drawn out over the platform and the grain thereon, the rake-head is elevated by the cam, and by the time the rake has reached the limit oif its outward movement its arm 13 is freed by the cam and the raketeeth drop upon the platform, after which, by the thrust ofthelink l', the rake moves inward, gathering the grain upon the binding-table. The conlin ued movement ofthe shaft G2 causes thecam to again elevate the rake and move it outward to draw in more IOO IIO

grain, and so on until sufeient grain to form a gavei is accumulated. out of operation at the proper time, so as to prevent interference with the bundling mechan- -.ism,by an incline, i', ou thebnder-arm striking against the outer end of an endwise-moving clutch-actuating rod, J, which rod passes at one end through an openingin the binder-arm support or standard G', and `is mounted at its opposite end in a support, j, on the frame of the machine. A spring, J', acts with a tendency to hold this rod in its normal position or to move itin a direction opposite that in which it is moved by the incliney 'i' on the binder-arm G. (-`ee Fig. 1.) An annularly-grooved collar,j', fast on the clutch-controlling rod J, is engaged by the forked end of a lever, J2, which is pivotetl to a lug,j2, and engages the sliding member J3 of an ordinary clutch-coupling on the shaft C2.

The operation ot' the devices for throwing the gavel-gatherer into and out of operation will readily be understood without further explana-tion.

Automatically-acting mechanism is provided for throwing the tying apparatus of the binding mechanism into and cut 0I"` operation. (See Figs. 1, 2,3, 7, and S.) This automatictyer-aetuating mechanism is connected with mechanism operated upon by the arrester or bundle stoparm D3.

rlhe before-mentioned movable or sliding section e2 ot' a clutch-coupling of well-known form on the shaft E, carryingthe chain-wheel b2, is acted upon by the spring k, the tendency of which is to slide the clutch-section e2 into engagement with thesection c and to hold it in place when so engaged. The forked end la' of a horiZontally-vibrating clutch shifter or lever, K, engages an annular groove in the sliding section c2 of the clutchcoupling. This shifter-lever is pivotcd to a lug, K', on one of' the frame-bars B, near its forked end, and its opposite or heel end is supported and guided in a suitable slot or way, -shown as formed by a bracket, k2, on the frame-bar H2. A

A link-arm or tlat bar, K3, is pivoted at 7c3 by one-end to the shifter-lever K, and is held against vertical play and guided iu its endwise movements as the lever vibrates by means ofa slot and a screw, 7c, passing through this slot and into a fixed supporting-lug, K4, attached to the frame-bar H2. This slotted link K3 carries at its outer end a verticallyvibrating cranked arm or elbowlever, K5, jointed by a pivot, 765, at its bevel or angle in a fork o1' slotin the link end. The downwardsite end to the inner end ot' an endwise-moving arm or link, L2, having a loop or slot, l', at its outer end, in which the vibrating bun- (lle-arrester and sizing-arm D3 works. The up- The rake is thrown per and shorter arm ot' the lever K5 projects toward the binder-arm actuating-shaft F2, and carries a roller, 765, at its end. A spring, K5, connects the longer or downhanging arm ofthe elbow-lever with its carryin g-lin k K3, nearits pivot, and this spring acts constantly with a tendencyto hold thelonger arm rocked inward and its shorter roller-supporting arm rocked downward to the extent ot' the movement allowed the elbow-lever by its connection with the slot l ofthe link-bar L. A properly-adj usted connection between this slotted link and the arm ot` the elbow-lever is made by pins L2 Z3, tted in holes in the lever and in the link-bar, as clearly shown in Fig. 8. A wiper or cam-projection, L3, on the shaft F2 operates in connection with the roller ofthe elbow-lever K5, and another cam, L4, on this shaft acts upon a stud or roller, Z4, on the side ot' a thrust-arm, L5, pivoted at its heel to the arm L', which is connected with the arrester D5. This thrustingarm L5, at its outer end, passes over and rests upon the binder-arm actuating-shaft F2, and is maintained in proper position during its reciprocations in suitable way, as by means ot a longitudinal slot and a screw, l5, secured to the frame-bar H2 and passing through this slot. The horizontally-vibrating arm L' is pivoted to a bracket, L5, on the frame intermediate its connections with the link L2 and arm L5, and the link L2, in operating with the ar' rester D3, is guided in its reciprocations by a longitudinal slot and a screw, Z5, passing through the slot and secured in a bracket, L7, which bracket serves also to secure one end of the before-mentioned arrester-arm spring d'. (See Figs. 1 and 2.)

From the above descriptionit will be understood that ou the accumulation upon the receptacle or table D' and against thebundle sizing and arresting arm D3 ot a sutjcient amount of grain by the operation of the gatheringrake D2the arrester will ne vibrated and moved back or against the strain of its spring d' until it strikes against the inner end of the loop or guide-slot Z' ot' the endwise-mcving link L2. When the grain pushes againstthe arrester with sufcient force to vibrate the arm L', to which this pushing force is transferred,

vthe movement of this arm, being imparted to the shifter-lever K by way ofthe link-bar L l and the reciprocating link-arm K3, will throw the clutch-section c2 into gear with the section c by allowing the spring 7c to perform its function, and the mechanism actuated from the shaft E is thrown into action for securing a bundle by the cord, which is tied hy mechanism yet to be described.

By referring' to Fig. 8 it will be seen that when the parts occupy their inoperative or stationary positions, as there shown, the roller h5 rests against the eccentric-wiper L3 at its extreme point or end most remote from the shaft F2, and the long arm of the lever K5 is rocked inward by its spring to the extent of its movement in such direction, or until ar IOS rested by the-stop-lug k7 bearing upon the un- *der side of the link-arm K3, near the pivot of the lever. In this position the roller-carrying arm of the elbow-lever andthe link-arm K3, by

their thrust against the wiper L3, hold the shifter-lever K 1n posi tion to prevent engagementof the clutch-coupling sections. Upon the actuation, as above explained, ofthe vibrating arm L by the gravel-,arresten and the consequent Vvibration of the elbowlever against the strain `of its spring, the roller 7c is rocked upward "carrying arm of the elbow-lever,'when in the position shown by Fig. 8, becomes, practicallyr considered, a rigid prolongation of the reciprocating linkarin K3, so that the shifter-lever K cannot be vibrated to release the slidingelu' ehsection so long as the wiper L3 bears against the roller k6. Shortly after the vibration of the elbow-lever by the looped link-bar L and` the starting into motion of the shaft F2 the wiper L4` on this shaft acts against the roller or lateral stud of the thrust-arm L5, and through its connections with' the gavel arresting, s'zing, and compressing arm D3 gives to this arma slight positive movement against the bundle to compress it and enable the tying mechanism to take cord out of the band for forming the knot. After the arm D3 has been elevated to release abundle by the action ot' the binder-arm actuating-crank, as before explained, it again falls -intoposition to check the incoming grain, and

the wiper L3 stops in position to dog the linkarm K3 by bearing against the roller k6 of the vibrating elbow-lever K5. Upon the downward movement of the binder-arm a bundle discharger or pusher, M, bears upon a b undle in event ot' its hanging and forces it downward until it bears on the ground orl is caught bythestubbleandleftasthemaehineadvances. The pusher is shown as formed by a pivoted lfollreiitled rod,jointed at m by its shank or upper end to a down wardly-projecting rod fastened to the binder-arm and its cum-grooved plate. The pusher is free to swing back and forth, or in a plane parallel with the path of the machine, so as to free the bundle and pre-` vent breakage in event ot' forcible resistance to the direct movement of the pusher.

The intermittingly-operated tyeractuating shaft F, thrown into and out of operation by the driving-shalt E, as before explained, has given to itone complet-e turn or a single revolution at each actuation. This shaft F, by means such -as next to he described, controls devices for clamping the cord as presented by the binder-arm, for adjusting the two ends of a band, for looping and knotting the band ends, and for severing the cord to release that portion of it forming the band about a bundle, and so allow of the discharge of the bundle.

A rotary earn carrier or disk, M', provided on its under face with a series of cam-tracks, is secured to the lower end of the shaft F, beneath the front inner end of the binding-table or grain-receptacle portion D of the platform A2. (See Figs. 11, 12,14, and 16.) This eamcarrier is covered and protected by a suitable casing, and the lower end of the shaft F is mounted in a bearing in the forward end of the base-plate M2 of this casing, so as to turn freely. The position in which the cam-carrier Vis shown bythe figures above referred to is that occupied by it shortly after having commenced to revolve and at a time when the binder-arm G has completed its descent and projected into the slot m of the tyer-casing. By the continued movementof the cam-carrier it acts by a cam track or rib, N, and an auxiliary cam-rib, n, upon a roller, m2, passing up through a slot in the cam-carrier and secured to the heel or inner end of an arm, M3, jointed at its outer end by'a pivot, m3, with the lower one, m4, ot' a pair of cord-directors. The upper one, M, of these two vihratin g cord placers or directors is fastened to the upper end ofan oscillating shaft, m5, to the lower end of which shaft the other cord-director, m4, is fixed atits heel and near its pivotal connection with the endwise-moving actuatingarm M3. The oscillatory movement of the shaft given it by the reciprocation of the arm or link M3 is thus caused to operate the two cord-placers simultaneously. The outward stroke or thrusting movement of the link M3 is imparted to it by the cam-track it and the heel of the track N, while the'inward or return stroke of thislinkarm to complete a ieciprocation and return the cord-placers to their resting or normal positions is imparted by the track N while act- Y ing at or near its front end on the roller fm2. It should be noticed that after this roller has been'passcd by the heel end ot' the main camtrack N, the rtciprocating arm M3, before its return or inner stroke, remains stationary for awhile during the action of the auxiliary cam u, and with the cord-directors at the extreme of their movement, and that al'ter the insti-oke of this reciprocating arm there is also apause in the movement of these cord-placers during the time the portion of the cam N which is concentric with the driving-shaft F is acting upon the roller m2. The arm M3, in addition to actuating the cord-placers, is made to act IOC) IIO

upon a reciprocating skeleton carrier-frame or yokeslide, O,for actuating a cutter, O, and a sliding carrier, O2, of a rotating and reciprocating swinging cordhook,o. To impart to the reciprocating arm M3 the function of operating the slide O by moving it inward, this arm is provided on its under side with a lug,

`as before explained.

o which, on-the inward stroke ot' the arm, abuts against a bracket, o2, fast on the slide O. As will be seen by referring to Figs. 1.1 to 15, inclusive, one arm ot' an angle-plate constituting the bracket o2.-is fastened to one side or yoke-arm of the slide O above the base M2, while the lower arm or horizontal projection ot' the bracket crosses beneath the arm M3, so as to be engaged by the lug o to retract the slide after it has been thrust outward by an edge cam or series of projections or inclines, o3 o4 05on the peripheryT of the cam-carrier M. This edge cam acts by its inclines successively, at shortintervals, upon theinelined or rounded :inner end, O3, of the slide, the leading cam-projection, o3, striking the slide at about or immediately after the time the auxiliary cam a begins to act on the roller m2. The knot is tied in a band, as presently to be described, while the cord-placers are at the extreme ofthe movement imparted to them by the outward stroke or thrust of the arm M3 and while the edge cam is acting on the slide O, from the incline o4 to the completion otl the thrust imparted to the slide by the incline o5. The cord is cut by the final action ot the incline o5 upon the cutter O', which, as plainly shown by Fig.12, is pivoted at the heel endto a fixed cuttingblade, O4, and linked atits outer end to an arm, o, of the slide O.

The main clamp or inner member of the reciprocating cord griping or holding devices is formed by a slide-bar, P, which at its outer end co-operates with the adjacent or inner end of Aan outer griper-bar-or sliding clamp, Q A strong spring, Q, acts upon the heel end ot' this outer member of the clamp with a tendency to move this clamp-section inward or toward the main clamp-section P, and to hold it in its inward position when it has reached the limit of its stroke in such direction.

Referring to Figsll to l4,inclusive, and detail views 37 to 44, inclusive, the various positions of the clamps during the bundling and tying operations will be understood by the aid of thefollowing description: The slide-bar P has a roller, p, mounted upon the inner or heel end of its shank or arm P', and this roller is acted upon by the cams N n ot the cam-carrier M inthe same way thatthe roller m2 is acted upon, In this way the outward or thrusting stroke is given to the clamp-bar P, and through it to the clamp-section Q, against the pressure ot' the spring Q', by the .abutting of the bar P against a shoulder, q, at the side of the bar Q.

The return or inward stroke of the clamp-bar P is in part given it by the cam N and is in part imparted by the spring Q.- It should be noticed that the contact-surfaces or points of contact of the cla mpslides P and Q are at the tops and near the sides or edges of these bars, next the point of the binder-arm G, when in the cord-slot q. The cord passes to the clamps by way of the rounded guiding-edge of the shoulder q of' the clamp-slide Q. More remote from the bindervhorn Q2 and nose q2.

'arm than lthc top cord-clamp formed bythe slide-shoulder q and end ot' the slideP there is a lower or auxiliary clamp, formed by an inner fixed member or stationary plate, It, beneath the bar P, and by attachments to the inner end ol' the clamp-slide Q, beneath the plane of its shoulder q. The clamp-bar P is supported on the plate R, and reeiprocates in a suitable guideway in the base-plate M2. The end of the clamp-plate R is formed with a slot or recess, r, as best shown in Figs. 3S and 42. A horn, Q2, forming a cord stop or arrester for the band end operated upon by thc lower cord-placer, m4, worksendwise in this slot r when the clamp-slide Q, to which it is fixed, reeiprocates. A shorter horn or nose, 12,011 the slide Q, also projects into this recess 1^ when the slide is moved inward to arrest the cord in position for engagement by the upper clamp. When the slideQis retracted or moved outward the nose q2 passes out from the slot y',

and the cord may then be directed past this nose into position to be held by the lower clamp, or between the end of the plate R (againstthe top and bottom walls of its slot r) and the end of the slide-barQ, intermediate the The horn Q2 abuts at its point against a stop, shown as formed by the inner termination or end wall ofthe slot r, to liniit'the inward movement of the slideQwhen the slide P is retracted, and so leave a space between the shoulder q and the plateRfor the cord to enter to the upper clamp and at such time be arrested by the edge ofthe projecting lower clamping portion of this slide at or near the base of the nose q2. When the cord is held by the lower clamp it serves to limit the inward movementot' the clamp-slide Q,the horn Q2 at such' time being arrested just short ot abutting against the stop. In Fig. 39 the end of the cord is shown as held in the lower clamp, as it would be left after securing a bundie and severing the cord, (see Fig. 44,) and the lower cord-placer, m4, is represented in section as in a position. occupied by it after having been started in operation to direct the cord from the binder-arm to the cord-holders to be engaged Atirst by the upper clamp.

By referring to Figs. 2 and l() it will be seen that the binder-arm is provided with notches s s, so that the cord-placers M4 m4 may engage the cord in the groove therein. In the positions occu ied b r the arts as shown in Figs.

37 and 38 the cord-placers have been vibrated to the extent otl their movement, leaving the cord in position to be nipped by the upper clamp. Figs. 40,41, 42, and 43 illustrate how the cord passes to the lower clamp by the corresponding action of the lower placing-hoger, m4, and suitable tension devices acting on the cord passing from the binder-arm, the cord from the binder-arm being in this way drawn into place inside the nose q2 to be clamped. At this time the two endsotthc band are held by the upper clamp, and the cord is not released until the lower clamp has taken its hold IOO IIO

on the cord. In Fig/.1.4 the end of the binderarm portion of the cord is shown as clamped. When so held the band portion ot' the cord is severed to release a bound bundle,ready for a repetition of the bindingoperations. Asshown by the latter figure, there is a short length of cord cutoff at the end clamped at the beginning of the operation. These Waste ends drop outof the clamps, their discharge being facilitated by the peculiarl form ot' the top portion of the clamping end ofthe slide Q, which is cut away and incl-ined, as at g3, inside of its shoulder g, so that the incoming cord is ena bled to push the waste end ont of the wayand to a position whereitwill not be caughtbythe upper clamp or interfere with the grping action.

The tying mechanism or cord looping and knotting devices are in part actuated by means ot' a slide-bar, P2, and its heel-roller p', operated upon by a cam-track, R'r'1'2,al1d an auxiliary cam ledge, R2, on the cam-carrier M'. The slide-bar P2 has two upwardly-projecting ]ugs,p2 p2, formed upon or secured to its outer end. These lugsengage an annular sliding collar or disk,P3, upon a rotary tubular ended spindle or cord-looping mandrel, P4, supported at or near its oppositeends in bearings in two brackets, psp", Which are secured to the baseplate M2 by means of posts 195105 296196. These posts form a guideway for the reciprocating yoke or sliding carrier-frame O, above which the mandrelbearings are located. A rotary and reciprocatingA cord-engaging hook, S, is supported byit's shank in theoutertubularend of the mandrel P4. (See Fig. 17.) This inner or sheathed hook of the knotter is connected at the heel end of the shank With the hub ot' the collar P3bya crosspin,s'. This pin passes through the hook-shank and collar-hub and plays in a slot, s2, in the mandrel as the collar reciprocates to impart the requisite endwise lnovementto the inside hook. this pin-andslot connection between the sliding collar, the hook, and the non-reciprocating rotating mandrel, the hook is caused to turn with the mandrel, while allowed to reciprocate without interference. The thrust or outward movementof the sheathed hook is given by means ot'a spring, S', encircling the mandrel and bearing atits opposite ends against the hub ot` the collar P3 and against a tixed collar, s3, on the mandrel.

The return movement or instroke of this hook is imparted by means of the slide-bar P2,aetuated bythecamcarrier, as will be understood by reference to Figs. 12, 14, and 15.

The outer or vibrating, reciprocating, and rotating cord engaging and loopinghook, o, ot' the knetter hasits turning movements imparted to it by the mandrel, and is reciprocated with the sliding carrier-frame O.

The sliding head or carrier O2 of the outside hook is mounted upon the squared or polygonal portion S2 ot' the mandrel P4, as clearly shown in Fig. 18, and is thus compelled to turn with,

While left free to'slide upon, the mandrel. A recessed or vertically-lugged bracket, T, on the outer end of the sliding frame O engages with an annular groove, t, in the hook-carrying head O2, and thus reciprocates this head. A longitndinal and radial slot, T', is formed in the head O2, as shown by Figs. 17 and 18,V and thehook o is pivoted in this slot by a pin, t'. A spring, t2, is secured at its heel end to the sliding head, and bears at its free end upon the heel ot' the hook, with a tendency to rock its opposite end, or the hook proper, outwar'dior away from the mandrel, and to keep the hook'heel against the mandrel or in contact with a tripper or hook-actuating incline, T2,thereon.v The inner surface or edge of the hook is recessed or doubly inclined, as clearly shown, to enable it to be operatedby the incline T2 and spring t2 to rock the hook away from and toward and against the mandrel. The rotary movements ofthe mandrel are imparted in such way as to canse it to turn in one direction somewhat more than a complete revolution, (about a reyelution and a halr",) and then to turn in the re verse direction, making, say, half a revolution, and stopping in a position corresponding to that occupied byit when firstacted on. Durfing the time the mandrel is being oscillated or turned first one way and then the other the cord is looped, tied, and severed and the knot cast ottfrom the mandrel. The mandrel is in this instance given its rotations from the shaft Fand its cam-carrier M' by mechanism now to be described, and as shown by Figs. 3, 1l, 14, and 16.

A pinion, U, from which one tooth is omiti ted, so as to form a space, u, between two of' the teeth nearly three times the size of that bretween any other adjacent teeth, is fastened to the inner end ot' the mandrel l?4 where it overhangs the cani-carrier. A sectorrack orcurved bar, U', toothed upon its under side, is fastened to the shaft F and cam-carrier. This rack has spaces u2 between each of its end teeth and the respectively adjacent teeth 'vcorresponding to the space u in the pinion, and is so enabled to readily and properly engage and leave the pinion without necessitatinga very nice adjustment of parts.

A pin, t', Figs. 11,14, and 16, is fixed to the mandrel near its inner bearing, and so als to rest or bear upon the top surfaceof the cam carrier or disk M', and near its periphery, to preventaccidental turning of the mandrel in one direction when not actuated by the rack U'. The peripheral or edge cams ofthe camcarrier are below the plane of the upper surface ofthe cam-disk, upon which the controller or stop-pin a bears, and the edge of this disk is recessed or cut away at V and V', as shown in Fig. l1 and indicated by the dotted lines, Fig.12. Whenthesector-raekengagesthemandrel-pinion the controller-pin (which had previously borne upon the cam-disk between the IIO IIS

recess V' and front end ot' the recess V, so as y to prevent movement of the mandrel in the direction imparted to it by the rack) works in the recess V, thus allowing the mandrel to be` turned and leaving the pin projecting about* in the direction shown by dotted lines in Fig. 16. The continued movement of the cam-carrier next causes a stud, e', thereon to strike the'pinion U to give the reverse turn to they mandrel and rock the pin c down into the re-v cess V, by the action of which, in connection with the stud e', the mandrel is set or its pinion U brought to the inoperative or starting po-l sition, in which it remains until the rack U again acts. In this position the stop-pin c dogs the mandrel against rotation in one direction, as above explained, while accidental:

turning ot' the mandrel in the opposite direction is prevented by a stop-lug, fw, and a spring or vertically-yielding stop-am, W, against the outer end of which this lug bears. When the mandrel is rotated by the sector-rack this stoparm yields, when the lug w rides up against its under side, and after that passes by the stoparm the continued movement of the mandrell in the direction given it by the sector carries this lug round far enough to allow ofthe back turn of the mandrel being' given it to bring the lug against the stop-arm.

During operation it will readily be understood by inspection of Fig. 2 that the binder-arm Gr remains stationary for a short time when in its eXtreme downward position, and so enables the vibrating cord-placers M4 m4 'and co-operating devices to operate properly.

y the cord-hooks and mandrel will be understood to be as follows: The end of the cord being held, the bundle accumulated, the binder arm caused to descend, and the Cord directors orv placers and clamps actuated as already eX- plained, the cord is presented to or pressed against the mandrel and held partly around it, as shown in Fig. 19. rEhe hook o next moves outward with its sliding head and swings against the mandrel, vas shown by Figs. 20 and 21, outside of the point about which the cord is held and subsequently Wrapped or looped. While the hook is closed against the mandrel it prevents displacement ot' the cord. By the rotation of the mandrel and outer hook the cord is wound and looped about them, the various stages of this winding and looping operation in the process of knotting being represented by Figs. 22 to 29. ln these and in the other figures beginning with the diagram 19 and ending with diagram 35 the extreme or clamped ends ol' the cord lor a band are indicated by thel letters :r x, while the letters yy indicate parts ofthe cord inside the knot or forming the band. By the time the stage in the knotting operation which is represented by Figs. 28 and 29 is reached it will be seen that the inside hook, S, has been advanced beyond the end of the mandrel, and by the time this projected inner hook has been turned into the position to engage the loopformed about the outer hook this latter hook has assumed the position shown by Figs. 30 and 31, to release its loop, which is drawn into themandrel by the return-stroke of the inner hook as the outer hook-carrier moves outward to cast off the cord. (See Figs. 32, 33, andt.) That portion of the cord wound about the mandrel forms au outer loop, which is cast ot` by the outward movement ofthe sliding head O2 and the vibration of thehook o. The in nerloop is drawn through the outer one and the knot completed and free to clear itselfof the hook S by the time the revolution in one direction of the mandrel and hooks is completed, as shown in Fig. 35. In the position of the parts shown by this figure the sliding head ot' the outer hook has been moved in far enough to close this hook down upon the mandrel. After this, and upon the finishing part of the instroke ofthe sliding head O2, the reverse turn is given to the mandrel to restore it to its starting or resting position. At about the stage in the tyingoperation represented in Figs. 32 and 33 the cord is severed and its end left clamped in the lower clamp, as already fully explained.

To provide for accumulating the grain into a compact bundle and so facilitate binding, two

guard-arms or grain-holderstT Y, (or one only of such guards, it' desired,) are provided, as shown in Figs. 45 and 46. Each arm is suitably pivoted at one end to the frame-work so as to vibrate vertically, in this instance by the bracket Z, and at its opposite end the arm is bent upward to form the grain guard or holder proper, Y', by which injurious rolling or scattering of the grain after heilig collected by the gatherer D2 is prevented. The grain being drawn in by the gatherer acts upon the inclined arms or shanks of the guards and elevates them, as will readily be understood from inspection of Fig. 45. As soon as the grain has been drawn inward past an arm, Y, this arm drops by gravity upon the bindingtable, behindthegrain, and by abutting against the grain prevents the spreading or separation ofthe stalks when freed by the gavel-gatherer.

I claim as of my own invention- 1. The combination of the platform, the grain-delivering apparatus thereof, the gavelevener, the pivot passing through its base near its outer end, and means by which the evener is vibrated to cause its vertical portion to repeatedly strike the butts of the grain, substantially as and for the purpose hereinbefore set forth. f

2. The combination of the platform, the grain-delivering bands or chains, the bindingtable, the vibrating gavel-e-vener, and the pair of driven pulleys, by connections with which IOO IIO
